Tattoos linked to lower skin cancer risk
Study finds tattoos may lower skin cancer risk, but experts urge caution.
Why it matters
- People with 2+ tattoo sessions had lower melanoma risk.
- Challenges assumption that tattoos increase cancer risk due to ink chemicals.
By the numbers
- Study evaluated 7,000 Utahns.
- 2+ tattoo sessions linked to lower risk of invasive and in situ melanoma.
- 1 tattoo session associated with higher melanoma risk.
The big picture
- Tattoos are common, especially among younger people.
- Possible explanations: better sun safety habits or immune response.
- More research needed to understand the link.
What they're saying
- Commenters suggest tattooed individuals may use more sunscreen.
- Others note potential trade-offs, like higher lymphoma risk.
Caveats
- Observational study; causal relationship unclear.
- Findings may not apply to other populations.
What’s next
- Further research to understand mechanisms.
- Study highlights need for more investigation into tattoo health impacts.
